What are Schleiden and Schwann known for?

Drawing of prokaryote eukaryote How can you tell a prokaryote from an Eukaryotic cell?

What are 3 functions of the cell nucleus?

FUNCTIONS OF NUCLEUS 1. Store genetic information 2. Regulate cell processes 3. Start the process of protein synthesis

Cell Part__Cell Wall Cellulose (structural carbohydrate) Function Support & protect Location Outside cell membrane __________________ The __cell wall ___is like a Analogy Drawing _____Because it___ _____________________

____ location of protein synthesis

Cell Part_______ Structure Mostly phospholipids plus some Protein channels & carbs. -= -- = Analogy: Function Regulate what goes in and out Location Outside of cytoplasm ___________________ The Cell membrane is like a Analogy Drawing _____Because it___ _____________________

Our cell membrane are complex with lots of moving parts. This allows some things to enter while keeping other things out.

Cell Part_____ Actual Drawing Structure Mostly water (cytosol) & organelles Function Site of chemical reactions Location Between cell membrane and nucleus ___________________ The cytoplasm is like a Analogy Drawing _______Because it _____________________

Cell Part_______ Structure: membrane bound organelle with green granum (look like stack of pancakes) called thylakoids. Function: use light energy, water & CO 2 to make sugar (energy storage molecule) Location: in the cytoplasm of Plants and some photosynthetic organisms ___________________ Analogy The chloroplast is like a solar collector because it converts light energy into another form of energy

Cell Part______ Structure Membrane bound sac with folded membranes (cristae) Function Release energy from glucose (sugar) Location In Cytoplasm of plant and animal cells ___________________ The mitochondria is like a Analogy Drawing _power plant Because it releases energy from fuel

Cell Part_____ Actual Drawing Structure Membrane bound sac Function Store water, sugar, and salt Location In cytoplasm in plants ___________________ The large vacuole is like a Analogy Drawing Bottle of gatoraide because it stores sugar salt and water

Lysosome Structure- membrane bound sac Filled with enzymes Function-Break down Lipids carbohydrates and Proteins. Location- in the cytoplasm Picture. Analogy-

What is this process Describe the movement of molecules during diffusion. What speeds up diffusion?

Diffusion Osmosis is the diffusion of water through a semi permeable (also called selectively permeable) membrane.

_____diffusion through channel protein Describe the movement of molecules during facilitated diffusion. Does this type of diffusion require ATP (energy molecules) to get started?

Describe the movement of the square molecules. Is energy required for this type of diffusion? What is the name of this type of transport? ?

Organization in living thingsfrom Multicellular living things are organized simple cell to complex organism. animal Place these in order from simplest to most complex.

What is meant by cellular respiration? brainstorm

Cellular (in cell ) Respiration (with oxygen) Plant & animal cells use sugar & oxygen to release energy. Cellular Respiration happens in the cell’s mitochondrion. The mitochondria put together the reactants, oxygen & sugar, and make the products carbon dioxide, water, and energy (ATP).

What is the difference between aerobic and anaerobic respiration?

Aerobic respiration occurs in the presence of oxygen. Anaerobic respiration occurs in the absence of oxygen. What are the runners doing once the race is over?

Anaerobic respiration occurs when oxygen is NOT present this is referred to as fermentation. Lactic acid formationdamages muscles fermentation – yeast forms alcohol

What 2 factors limit cell size?

Cell size is limited by 2 factors: 1. When a cell gets too big the DNA gets overworked & fails this is called DNA overload. 2. Cells that are too large can not get food in and waste out and the cell dies.

As cells get larger their volume increases and they can’t get food in and waste out effectively. How can a cell prevent DNA overload and excessive volume from occurring while continuing to grow?

1 cell becomes 2 genetically identical cells. Making somatic or body cells.

Cells divide to reduce their volume making it easier for the DNA to control all processes and making it easier to transport food and waste throughout the cell efficiently.

What is it called when cells reproduce out of control? Cells gone wild!!! Normal Cells

Cancer is caused by uncontrolled mitosis (uncontrolled cell division) due to a change in the DNA. Malignant cancer cells can migrate to other parts of the body and spread cancer to those areas.

DNA What is this structure called? What does a DNA nucleotide monomer consist of?

Chromosomes are made of DNA

What is this process called.

What are the steps of DNA replication?

Compare and contrast DNA and RNA DNA ONLY Both RNA ONLY

Relation between gene and protein. Genes are the recipe for making proteins

When DNA is rewritten as m. RNA the process is called ____.

m. RNA Decoder Wheel

m. RNA Decoder Chart

In this part of protein synthesis you go from the language of nitrogen bases to the language of amino acids it is called ______ 3 letters of m. RNA that code for an amino acid is called a ____

A gene mutation affects one gene. Chromosomal mutations affect many genes. Both can be deadly. What can be used to diagnose a monosomy or trysomy?

What sex is this person?

Genetic Engineering – humans changing the genetic code.

What is this process called. How is it done?
